"If engine is cranking but not firing and no fuel is reaching the rail I`d be suspecting the crank sensor. Any spark at the plugs? EML lit or flashing when cranking?"

I would have thought the fuel pump would prime the system for a moment after turning the key? Or is that not the case with the Omega?

But no fuel when cranking either, Ive not checked for spark yet. No EML light, but I'm not convinced the bulb is OK Ive never seen it light up before.

Anyway that's given me a few ideas to check out tomorrow evening and given me confidence that I am not fighting a loosing battle with the key gone.

Ive not tried the paper clip test as I was going to hook it up to the laptop tomorrow evening, perhaps I should have done that before posting!! But was starting to get a bit fed up with it earlier.

Cheers

Omega General Help / Is it possible for key to lose its sync with the ECU?

« on: 02 October 2012, 19:42:25 »

Hi,

I have just finished changing both the head gaskets on my 1999 3.0L Omega, on and off it has taken about 2 months. But now it just wont start, I have double checked all connections to no avail.

I have checked the fuel and ignition relays and although there is power coming to them OK there is no earth pulse from the ECU to pressurise the fuel rail before trying to start it. If I bypass the relay and pass power straight to the fuel pump the pump works OK so not a pump issue.

The only thing left I can think of that's causing it is the key transponder has lost sync with the ECU. I have  been using the key manually for about a year after the battery contacts came apart, but with the car battery disconnect for a couple of months is it possible to lose sync?

Any ideas?
Cheers
Phil

Omega Electrical and Audio Help / BOSE default volume adjustment?

« on: 22 September 2011, 13:08:44 »

This is really doing my head in but I cant for the life of me work out how to change the default volume on my BOSE PHILIPS in a 1999 Elite. I have to turn it up after every time I restart the car.
I found a work around, by turning if off before switching off the ignition it will then come back on at the same volume, but I normally forget to.

Does anybody know if and how it can be done?

Cheers
Phil

Omega Electrical and Audio Help / Injector common, +ve or -ve?

« on: 12 September 2011, 19:22:40 »

I am hardwiring my LPG loom into the injector loom but I need to know if the common is +ve or -ve.

Ive tracked through the Haynes wiring diagram and think it is +ve as I've always come across before but just wanted to be 100% sure before cutting anything.

can anybody confirm?

Cheers

Omega Electrical and Audio Help / Re: One too many plugs left over after engine refit!

« on: 10 June 2011, 16:23:52 »

Thanks for all the input, it was the knock sensor one. I had plugged the knock sensor into the temp sensor. All sorted know expect the bigger problem is it fired up and ran lovely for 15 minutes before seizing again.

Thanks for the tips everyone, I off out there again in a bit to have another go at it, still got to work out where all the little black vacuum pipes go yet too. Ideally I need to find somebody locally with the same car so I can compare.

Its too short to reach that far back, Its only comes out of the loom cover about 3 inches and I can't see anything within reaching distance apart from the idle valve but its a different fitting and Ive found what appears to be the one for that.

I forgot to mention its a male connector.

Omega Electrical and Audio Help / One too many plugs left over after engine refit!

« on: 09 June 2011, 20:27:24 »

Ive just refitted the X30XE engine in my 1999 Omega Elite and have a "spare" wire connector which for the life of me I cannot work out where it goes. Its a two wire connector the comes out of the plastic loom case that runs adjacent to the cam cover and plenum on the oil filler cap side, the wire exits the case just below the idle valve and in front of the oil filler neck. Has any one any ideas where it is supposed to go?

Many thanks in advance,
Phil.

Omega General Help / Re: code 16 knock circuit 1.

« on: 21 August 2011, 19:46:09 »

That's why I love this forum, As soon as I saw your reply I remember hearing a small rubbing noise that didn't last long and I soon forgot about, but  sure enough a quick check there and found the wire has practically rubbed right through. Hopefully that will be that and you will have saved me hours of head scratching.
Cheers

Omega General Help / code 16 knock circuit 1.

« on: 21 August 2011, 17:50:20 »

Hello,

I took my inlet manifold off my 3.0 yesterday to fit the one id set up with the LPG conversion but it wasn't running right afterwards and was giving a code 16 "Knock circuit 1" message, I assumed it was part of the LPG throwing it up so removed it all and refitted the original manifold but the problem has not gone away, it shows intermittent loss of power especially noticeable when pulling off. Ive some spare knock sensors I was going to try but does anyone know which side No1 is? and do you recon that will cure the problem?

Cheers
Phil

Omega General Help / autobox P1605 error Internal Control Module

« on: 16 August 2011, 21:06:03 »

Hello,

Just did a full fault code check on the car this evening and found a few which I expected but also one for the gearbox which is slightly worrying the messages is:
 
"My Naff Code Reader" - KW2000 Communication Window> 1999 (X)|Omega-B|Transmission|AR 25/35

Keyword #1: 6B
Keyword #2: 8F

Does anyone know if this code is referring to an internal solenoid or the actual gearbox control unit not being recognised?

The gearbox all works fine as far as I can tell and I recently did an oil and filter change on it. But if there is a problem Id like to get it sorted.

Cheers
